CaseHPOFreeText: progressive paracentral scotoma OU, progressive visual impairment OU (blurry vision). BCVA: OD-0.1, OS-0.22. Tension: 13mmHg/14mmHg. FAF: bilateral hyperautofluorescent macular and peripapillary spots, few spots of paracentral retinal atrophy (foveal sparing). Autofluorescence and deposits (severity): deposits medium, atrophy low. OCT: hyperreflective spots, partially invading into the outer retina, partly confluent lesions of cRORA, foveal sparing, degenerative intraretinal fluid. Central macular thickness: 328µm/322µm. Macular volume: 9.31mm³/9.00mm³. mfERG: bilateral amplitudes in normal range, slight relative reduction in the paracentral areas. Fluorescein angiography: bilateral dark choroid, mild paracentral dye pooling in the late phase. Color vision: Inconspicuous. Clinical examination: pattern-like distribution of the lesions.
